lb Hui/1 0111 it may comm/wt:

Be it known that 1, JOHN A. WnERRY, a citizen of the United btates,residing in New Orleans, in the parish of Urleans and State of Louisana, have invented certain new and useful improvements in'lype-writing'iuachines, or which the following is a specificatlon.

This invention relates to the ribbon-vibrating devices or type-writingmachines.

the object or the invention is to provide simple, inexpensive, andeasily-applied and other-arse improved means for shifting the ribbonrelatively to the printing-point so as to cause the type impressions tobe made along either edge of the ribbon, especially Where the edges aredifferently colored.

Accordmg to my invention 1 substitute for the single-precc-nbbon carrierwhich is usual in the Underwood and other writing-machines aribbon-carrying member comprising two parts, the lower of which engagesthe usual vibrating lever and the upper or which carries the ribbon andslides up and down upon the roller to bring dill'ercnt edges of'theribbon over the printmg-point, the extent 01 throw of the ribbon atihe'type-stroke's being the same in all cases. Upon said ribbon-carryingmember 1 provide a third part, which is ad ustable to en'ect theshifting of the upper or ribbon-carrying part, and this third men1- heris controlled by means of a finger-piece mounted upon the framework, sothat by cover the printing-point.

moving the linger-piece in either one direc tion or the other the ribbonis shifted to bring one color or the other into use.

Other features and advantages will hereinafter appear.

in the accompanying drawings, Figure l is l a rear perspective view of apart of the Underwooc trout-strike type-writing machine provided with myimprovements, the parts bemgadjusted to bring the lower color-band ofthe ribbon over the printing-point.

Lower-case and upper-case types 1 and 2 are mounted upon bars 3, pivotedupon a rod 4, to strike against the front side or a platen 5. The barsare mounted in a segment 6, connected to a framework 7 and having atype-guide 8, the type-bars having heels 9 to push rearwardly acurveduniversal bar 10, llXed upon a horizontal moving frame 1 1, the latterhaving an arm 12, slotted to engage a wrist 13, provided upon aforwardly-extending lever 14, which vibrates up and down at everytype-stroke. Saidlever is mounted upon a bracket 15, secured upon a rail16. bpon said rail runs a roll 17, belonging to a traveling frame (notshown) which carries the platen 5. Said rail and platen-frame areshiftable up and down with'thc platen to enable the din'erent types 1and 2 to print. As so far described the parts are in common use upon theUnderwood type-writing machine. The usual biclnome-ribbon, having an upper color-band 18 and a lower color-band 19, -1S tln'eaded through eyes20 in a ribbon-carrier (designated generally as 21) and provided with avertical shank 22, which is inserted in a socket formed by bending ears23 upon the upper end of a stem 24, so that said ribboncarrier can slideup and down upon said stein. At its lower end the latter is detachablypivl oted at 25 to the forward end of the vibrating l lever 14, so thatthe stem is caused toreciprocate by the vibrations of the lever.

A plate 26, having a cam edge 27, is mount ed to slide horizontallyacross the reciproeating stem 24, being for this purpose held in 1suitable ears or socket-pieces 28, whereby the member 26 is caused toreciprocate up and down at the type-strokes with thestcm 24.

21s a view of the lowerot the two parts, which l The. sliding movementsof the member 26 are togetherform the ribbon-carrying member. i limitedby a pin 29, projecting through a slot big. 3 is a side sectionalelevation illustrating 30 in said part 26. The cars 28, as well as theribbon as brought up to cover the print- 1 said pin, are provided uponcross-arms 31 32, ing-point. Fig. 4 1s a rear elevation, partly formedupon the lowcrportion of the stem-24. in section, of the ribbon-carryingmember, At l ig. it-tho shank 22 of the carrier .21 is showing the sameadjusted in such ainanner seen resting upon the slide 26, so that the asto cause the upper portion of the ribbon to Fig. 5 1s a fragmentary sideelevation illustrating the upper latter serves to transmit upwardmovement from the stem .24 to the carrier 21, the latter returning withthe stem 24. to normal position during the movements of the type-barsaway from the platen. Although the stem 24 is preferably not positivelyconnected to the carrier to return the latter, still it will beunderstood that the ribbon when elevatedby the carrier exerts adownwardreaction upon the latter, and this downward tendency isv aidedby the weight of the carrier, so that it always returns properly tonormal position. When the slide 26 is moved to the left at Fig. 4, thecam edge 27 acts ,upon a cam 33, formed upon the lower end of the shank22,

- to lift the shank relatively to the stem 24, as

atFig. 1,-in which position the lower colorband 19 is brought into useat the typestrokes. This movement of the slide 26 is efiected'by-afinger-piece 34, provided upon the end of a slide or rod 35; supportedby brackets 36 and having at its inner end a downward-extending fingeror part 37 to engage an eye or ppojection 38, provided upon the slide26. hen the finger-piece 34 is pulled out, Fig. 1, the point or cam 33of the ribbon-carrier shank 22 rests upon the top edge of the slide 26and maintains this position during the actuation of the types.Accidental displacement of the stem 22 is prevented by a pin 38 in thestem 24 engaging a slot 39 in the shank 22. When the ringerpiece 34 ispressed in, the slide 26 is moved to the Fig. 4 position and theribbon-carrier 21 drops by its own weight, aided by the downward tensionon the ribbon, to the Fig. 4 position, thereby bringing the color-band18 of the ribbon into use at the type-strokes. It will be seen that thedevice 26 communicates movement during the type-strokes from thereciprocating part 24 to the ribbon-carrier 21 and is adjustablerelatively to both said carrier and said reciprocating part, so as toshift said'carrier either toward or away from said reciprocatingpart tocause different portions of the ribbon to overlie the printing-point,and thatthe finger-piece 34 is stationary or inactive during thetype-strokes, but is connected to means for effecting relative shiftingmovements of the parts 21 and 24.

Variations may be resorted to within the scope of the invention, andportions of my improvements maybe used without others.

Having thus described my invention, I claim 1. The combination of aribbon-carrier, a part which reciprocates at the type-strokes, and adevice communicating movement from said reciprocating part to saidcarrier, said device being adjustable relatively to both said carrierand said reciprocating part and having the form of a cam to shi't't saidcarrier relatively to said reciprocatingpart to cause a diit'erentportion of the Width 6f the ribbon to overlie the printing-point. 2. Thecombination of a ribbon-carr ier, a

reciprocating support upon which the carrier is mount ed, and a camengaging said support and said carrier for shifting the latter upon thesupport to cause a different portion of the ribbon to overlie theprinting-point.

3. The combination of a ribbon carrier having a shank, a reciprocatingste'm having a socket to receive said shank, a cam mounted to slidetransversely upon said'shank to adjust said ribbon-carrier, and a stopfor limiting the movement of" the cam.

4. The combination of a ribboncarrier having a shank, a reciprocatingstem having a socket to receive said shank, a cam mounted to slidetransversely upon said shank to adjust said ribbon-carrier, a stop forliniting the movement of the cam, and a finger-piece mounted upon thefranting, and stationary during the reciprocations of said member, butconnected to said cam for shifting the same. a

5. In combination, a reciprocating memrooation, and loosely connected tosaid projection.

6. The combination of a ribbon-carrier, a reciprocating support uponwhich the carrier is mounted, a cam interposed between said support andsaid carrier to shift the latter upon the support to cause diflorentportions of the ribbon to overlie the p1inting- )oint,

said cam reciprocating with said support and said can ier, and afinger-piece mounted upon the fran ewoik and loosely connected to saidcam for shifting the latter.

7. ,The combination of h aving a shank, a reciprocating stein having asocket toreceive saidshank, a cam engaging said shank and said carrierfor sliding the shank upon the cart ier, a stop for limiting theshitting movement of the cam, said cam mounted to reciprocate with saidstem and carrier, a slide niounted upon the framework and having afinger-piece and movable across the line of reciprocationof said stem,and having a finger or part extendingparallel with the directionofniovenzent of said stem, and an eye upon said cam to engage saidfinger.
